Patent CA-2078615-A1 (CA)
Title: Shaft seal
Inventor: BOURQUE ROBERT F
IPC: F16J15/30
Filed: 1992-09-18
Abstract: ABSTRACT OF THE DISCLOSURE         A shaft seal comprising a plurality of members which   collectively   engage  the   shaft   exterior in substantially uninterrupted 360° sealing contact in a plane perpendicular to the axis of the shaft while providing relatively  high  capacity  for  wear  using  nonflexible materials such as graphite.  The provision of 360° contact in a single plane enables engagement between the shaft seal and the shaft to be limited to a single ring structure, rather than requiring a pair of rings  in side-by-side abutting relation.  The seal members comprise a plurality of followers and an equal plurality of drivers, with each of the members being movable inwardly as it wears.  Each of the followers is driven inwardly by drivers on each side as it wears.  Each follower has a wear surface configured for sealing engagement with the shaft, and a pair of bearing surfaces for engagement with drivers on either side.  Each of the drivers has a pair of bearing surfaces for engaging the respective bearing surfaces of the followers on either side, and a central wear surface for engaging the shaft. The bearing surfaces of the drivers and the followers are substantially planar,  and the bearing surfaces on each driver are preferably coplanar with one another.          In  some  embodiments  of  the  invention  the followers and drivers are each four in number.  In other embodiments the drivers and followers are each three in number.   The drivers and  followers may be made of a graphite ceramic material and used without lubrication, or alternatively may be made of a babbitt material or other conventional material for use in a lubricated environment.

Title: Valve plate for a sliding gate valve on a vessel containing metal melt
Inventor: WALTENSPUEHL ROLF
IPC: B22D41/32
Filed: 1992-11-18
Abstract: Abstract The refractory valve plate (22) for a sliding gate valve (20)  on  a vessel  (10)  containing metal  melt has  a refractory plate (31) with a recess on its side directed away from the sliding surface (22') which broadens the flow opening (25) and in which a highly refractory insert (30) is embedded which, together with the adjoining plate (31), defines a gap (32) which communicates with the flow opening (25) and which serves for the injection of gas.          This gap (32) is preferably formed as a free clearance in which the insert (30) rests directly on the refractory plate (31).  An annular gas chamber surrounding the gap (32) is coupled to a gas connection (33).  The gas can thus be blown constantly or impulsively into the flow opening (25) of the sliding gate valve (20), particularly in its closed position, and freezing of the steel melt situated therein may thus be successfully prevented.  The result of this valve plate (22) in accordance with the invention is that optimal gas injection is achieved with very simple manufacture and with a high service life.     (Fig. 1)

Title: Process for transmitting a time-variable control parameter
Inventor: MIELKE JUERGEN
IPC: H04H20/76
Filed: 1991-06-26
Abstract: Abstract For individual tuning of the dynamics of a radio programme signal (variable dynamics), a control parameter is derived from the associated radio programme signal and emitted together with the programme signal.  At the receiver, the control signal is used to select reproduction dynamics differing from the transmitted programme-signal dynamics. For transmission purposes. the control parameter is inserted as a digital auxiliary signal in a data stream which is transmitted asynchronously to the programme signal in a programme-signal-free region Or the transmission band. The digital auxiliary signal is inserted at intervals as a data packet with varying advance with respect to the programme-signal section concerned. The variable time differences between the points in time at which the data packets are inserted and the occurence of the programme signal sections are transmitted as sepa-rated lime information in the data packets and used at the receiver to synchronize the advanced control signal with the pro-gramme signal.

Abstract: Abstract of the Invention A method of controlling pitch deposits in a pulp and papermaking process comprising adding lipase and a cationic polymer to a cellulosic slurry in amounts effective for diminishing pitch deposits from the cellulosic slurry in a pulp and/or paper mill. The method may include adding lipase and a cationic polymer to a cellulosic slurry in amounts effective for both reducing the triglyceride content of a cellulosic slurry by hydrolysis and diminishing the concentration of fatty acids released by the hydrolysis in the aqueous phase of a cellulosic slurry. The triglyceride hydrolysate content of the aqueous phase of a cellulosic slurry, formed by the action of lipase on triglyceride within the cellulosic slurry, is reduced when the amount of lipase and the amount of a cationic polymer is maintained for a time period sufficient to hydrolyze at least some of the triglyceride in the cellulosic slurry and reduce the triglyceride hydrolysate in the aqueous phase of the cellulosic slurry.
Patent CA-2102448-A1 (CA)
Inventor: SIAK JUNE-SANG
IPC: B01J13/00
Filed: 1993-11-04
Abstract: A method is provided for forming a sand core which is suitable for use in casting processes, and in particular squeeze casting processes, to form internal features and intricate external features of a cast article. The core forming method involves the use of a single-component gelatin binder whose degradation at elevated temperatures is catalyzed by additions of a ferric compound. The gelatin binder is a mixture of proteins derived from amino acids such as glycine, L-proline, alanine, L-glutamic acid, L-aspartic acid, and/or small percentages of others, such that the gelatin binder is water soluble and therefore easily eliminated from the core sand at the end of the casting process. Due in particular to the presence of the ferric compound, the gelatin binder readily degrades at low temperatures, such as those associated with aluminium casting processes, such that the core degrades sufficiently to permit the sand to freely flow from the cast article without the need for core removal operations. Finally, the gelatin-based binder is nontoxic, such that its elimination from the sand to reclaim the sand for reuse does not pose an environmental hazard.

Title: Semiconductor Type Differential Pressure Measurement Apparatus and Method for Manufacturing the Same
Inventor: IKEDA KYOICHI
IPC: G01L19/06
Filed: 1993-09-08
Abstract: A semiconductor type differential pressure measurement apparatus comprising a measuring diaphragm whose periphery is fixed and two measuring chambers each having a predetermined spacing along both surfaces of said measuring diaphragm. The apparatus detects differential pressure within the allowable limit of measurement, but when an overpressure is applied, the measuring diaphragm is directly backed up by the wall of the measuring chamber to prevent the diaphragm from being damaged by the overpressure. Accordingly, the apparatus requires no additional protective mechanism against overpressure.      The apparatus comprises an additional chamber accompanied by an overhang provided in such a manner that the effective area thereof may be larger than that of the opening of the chamber. Accordingly, the force which is exerted to the joint portion between the silicon substrate and the support substrate upon application of an overpressure can be greatly reduced.      Two measuring chambers each having a predetermined spacing are provided along both sides of the measuring diaphragm. Accordingly, the exterior of the semiconductor differential pressure measuring apparatus according to the present invention may be exposed to open air, and thereby no particular pressure-resistant casing is necessary. In further detail, the sensor portion need not be covered with a pressure resistant vessel as in the apparatuses of the conventional type in which the measuring pressure is applied externally to the sensor, The semiconductor type differential pressure measurement apparatus according to the present invention comprises a conductor connection formed by introducing impurities into the joint surface between the silicon substrate and the support substrate, and one end thereof is further connected to a strain detector element.      Accordingly, no pressure-resistant hermetic sealing is necessary in extract an electric signal.

Title: Discriminating Charger and Compatible Battery
Inventor: SPELLMAN PATRICK
IPC: H01M50/548
Filed: 1993-10-28
Abstract: A charger for a rechargeable alkaline manganese (RAM) battery has a positive contact which engages against the positive terminal of a compatible battery without making electrical contact with the positive terminal protruding nubbin. A rechargeable battery has an insulating jacket which surrounds the battery side wall but which does not overlap the positive terminal. Hence the charger positive contact may engage against the specially adapted battery and electrical contact, but will not make electrical contact with a conventional battery having a partially insulated positive terminal. Alternatively, the battery positive terminal may be insulated within less than 0.040 inches of the battery perimeter and be charged by protruding positive contacts spaced inwardly from the perimeter by approximately the same amount.

Title: Diving mask with lenses and method of fabricating the same
Inventor: KRANHOUSE JON
IPC: A61F9/02
Filed: 1994-03-17
Abstract: ABSTRACT OF THE DISCLOSURE      A diving mask having hemispherically-shaped lenses mounted on a flexible gasket or portion and fitted to the contours of a user's face. Laser scanning or topographic mapping is used to determine the contours of the user's face.  Edges of the hemispherically-shaped lenses are then shaped to fit the contours of the face.  As a result, the spherical center of the lenses substantially coincides with the optical nodal point of the user's eyes, or the center of rotation of the eyes.   This virtually eliminates the phenomenon of underwater magnification-distortion caused by the difference in refractive indices of water and air. The diving mask may also have hemispherically-shaped lenses mounted on a support portion.  The support portion, in turn, is mounted on a flexible gasket of selected size.  A secure seal is provided between the diving mask  and a user's face by the flexible gasket.  The diving mask may be provided with at least one purge valve.  The diving mask may be used with retractable corrective lenses, is desired.  The diving mask may be used with bottom lenses which provide vision both above and below water. Hemispherically-shaped meniscus lenses may be used with the diving mask.   The meniscus lenses are designed to provide optimal peripheral vision, while reducing weight and facilitating drainage of water from the mask.
